If you have the skills, you do both, by day trading and holding bitcoins for long periods of time. To me both are interesting in terms of crypto, this is inseparable from our knowledge. This ability is not only financially based, but analytical skills are also very important. I recommend holding bitcoins, but you should also do day trading.
You could actually do both if you are really that capable but of course you do need funds too for you to invest on because this is the main requirement on dealing both things.
As long you do know on what you are doing and able to handle it out on your vacant time or even going with full time then this is really an advantage but you should mind about the risk involved
would be double since you are dealing with both things but once you do able to make profit on both things then that would surely give out some significant one.
